What is a Rebreather and How Does It Work Part 1 Presented By Scott's Scuba Service 

Lol Jenny is very jumpy! and glad you liked it. We want to do some more videos in this series. There is alot to learn about diving. The first step is getting that open water class and just getting in the water!

Glad you liked it!

That is on my short list of videos to do next!! Thanks for the comment, it makes me really want to get filming

Hello! We've had alot of folks as this and we are planning on making part 2 this fall. Our shop has been super busy this summer which has slowed down our video making.

Robert C. Vennum Jr. he’s watching you 😂

Only when you begin and end the dive. The system automatically (or manually if you choose to fly it that way) adds small amounts of Dil and O2.

@@bluedescentphotos as I’m still very afraid of this, if I ever do scuba I think I’m just going to stick with a standard open circuit >~

@@jakeb.7997 There is nothing wrong with that. Starting standard scuba is the best, and really only, option anyways. Someone should be very confident and comfortable with open circuit scuba diving before considering a rebreather. Once a diver is ready though these systems are amazing.

Unfortunately not yet, our summer has been super busy with the shop, but this fall/winter we plan on making the video!

Hello, a great many things determine how long you can stay underwater on a rebreather. Typically that amount of time is based on your scrubber life. Depending on many factors 4-6 hours is a safe guess on a max dive length. You have to be very careful not to overbreathe your system or the scrubber cannot do it's job of removing the CO2 properly (because it is a chemical reaction there needs to be some rest time). You could run yourself out of O2, but if you have entered the water with a full tank that is typically not a determining factor in your dive length. You use very little gas volume while on a closed circuit rebreather.

Great question! Rebreather divers always carry at least one bailout bottle. The size and number of bailout bottles depends on the dive that is being done. If the rebreather would malfunction or fail the diver would bailout to open circuit and terminate the dive.

LOL so true

That would require on-board electrolysis. While technically possible, it is a slow process. Now that’s just with pure water. Electrolysis on salt water produces different biproducts, sodium hydroxide and chlorine, which are both not something you’d want to breathe.

@@flakdampler11 I was thinking free oxygen in the water. as for the CO2 we breathe out no Cl. but that's just the miracle I thought a rebreather did. I thought they had figured out how to be a fish.

@@gdotone1 oh yeah that would be cool. It’s probably possible to make something that works like gills. I wonder what the limitation is.

@@flakdampler11 i imagine size at first. i bet the military already has such. probably classified beyond top, top secret. theirs might desalinated the salt water, using either a membrane, or catalyst, or enzyme, or electrolysis to get the oxygen out of water. lol.
